What gets me are the video card overheating problems this game creates despite running like crap and really not being all that demanding graphically. I've got a GTX 670M in my laptop (That's not exactly a slouch) and the game is virtually unplayable on it. I've got three GTX 780 Ti's in my desktop machine and at 7680x1600 the frame rate isn't where it should be. I get faster FPS out of Crysis 2, Mass Effect 3, Battlefield 3, etc. There is simply no excuse for it.
Issues like like ability lag, server lag spikes, and generally poor performance should have been addressed either before launch or shortly thereafter.
The game doesnt cause overheating issues. The GPU drivers do because there are no game specific profiles for SWTOR. The GPu has to rely on generic instructions for the drivers unless the user creates their own profile.
